Pioneer ROMS

I have two questions. Is there a typo in the guide regarding the 14B? This unit does not have an IR port (or does it? I don't have mine in front of me). I know that Emu42 is advertised as being able to emulate it, but how does one obtain the ROM in a legal manner if there is no IR port?

That said, how does one go about obtaining the ROM of non-IR Pioneer units -- in a legal manner. For example I have seen screenshots of the HP 20S being emulated, but how would I go about copying my HP 20S's ROM? I wonder if a chip reader was used.
